Texture map of paint colors, and its production method, production program, production system and data structure

Abstract

The present invention relates to a texture map of paint colors in which a plurality of paint colors are arranged to be able to identify their textures; and its production method, production program, production system and data structure. The texture map of paint color production method of the present invention is a method of producing a paint color texture map in which a plurality of paint colors are arranged on a two-dimensional plane using coordinate axes of two parameters that represent the color and texture of the paint colors, the method comprising: determining at least three characteristic quantities, using a plurality of spectral reflectances measured at a plurality of light-receiving angles, for each of the plurality of paint colors (S1 to S3); subjecting a data group including the at least three characteristic quantities to principal component analysis so as to determine a First Principal Component and Second Principal Component expressed as linear expressions, using the characteristic quantities (S4); calculating values of the First Principal Component and Second Principal Component for the plurality of paint colors; and positioning the paint colors on a two-dimensional plane that has the First Principal Component and Second Principal Component as the two parameters and has values of the First Principal Component and Second Principal Component as coordinates (S5).

Description

TECHNICAL FIELD[0001]The present invention relates to a texture map of paint colors in which a plurality of paint colors are arranged on a plane by their textures; and its production method, production program, production system and data structure. The texture map of paint colors is a color map in which a plurality of paint colors are arranged on a plane. The map may be in the form of an image displayed on a color display apparatus, or in the form of an image printed on paper or a resin film.BACKGROUND ART[0002]When improving the marketability of an industrial product, the exterior design is as important as the basic performance and mechanism of the product. Color is a significant part of the exterior design. In addition, it is a usual practice to coat industrial products for the purpose of protection or improving appearance. Therefore, it is a designer's task to determine the paint color in consideration of functions and characteristics of the industrial product, the customer's req...

Benefits of technology

[0024]The present invention enables classifying and arranging paint colors by positioning a plurality of paint colors, including not only solid colors but also metallic colors, on a plane with coordinate axes of two parameters expressing the color and texture of the paint colors.

[0025]This paint color texture map of the present invention enables visualization of the impressions of colors described with abstract words. More specifically, the texture map of the present invention allows the paint company designer to easily specify the color even when the client describes the color abstractly. Therefore, the paint color texture map of the present invention eases communication among people involved in the color design.

[0026]The paint color texture map of the present invention may be stored in a computer-readable recor

Problems solved by technology

Therefore, color texture requests from a manufacturer's designers are often misunderstood by the paint company designers who actually design the paint colors.

This has causes difficulty during the design of paint colors of industrial products.

However, this method is still incapab
